  • Each of the speaker casings 22 is made at least partially of an elastic material capable of absorbing vibration generated by the speaker drivers 24 and resonance resulting from such vibration.
  • each of the speaker casings 22 is formed as a single piece that is made entirely of a rubber material selected from the group consisting of silicone rubber (SR), natural rubber (NR), isoprene rubber (IR), styrene-butadiene rubber (SBR), butadiene rubber (BR), polychloroprene rubber (CR), butyl rubber (IIR), nitrile rubber (NBR), ethylene-propylene rubber (EPM), and ethylene-propylenediene rubber (EPDM).
  • silicone rubber SR
  • NR natural rubber
  • IR isoprene rubber
  • SBR styrene-butadiene rubber
  • BR butadiene rubber
  • IIR butyl rubber
  • NBR nitrile rubber
  • EPM ethylene-propylene rubber
  • EPDM ethylene-propylenediene rubber
  • the speaker casing 22 of each of the speaker assemblies 20 has an inner surface, and includes at least one elastic rib 25 extending radially from the inner surface.
  • six of the elastic ribs 25 are formed extending radially from the inner surface of each of the speaker casings 22.
  • the front frame 21 and the rear frame 23 abut against the elastic ribs 25, that is, the elastic ribs 25 are interposed between the front frame 21 and the rear frame 23 to thereby separate the front frame 21 from the rear frame 23.
  • each of the speaker casings 22 has a bottom surface, and at least one reception hole 26 is formed in the bottom surface.
  • a pair of the reception holes 26 is formed in each of the speaker casings 22, and each of the reception holes 26 is defined by a concave hole-defining wall (see Fig. 5 ).
  • the stand 30 has an upper surface, and a plurality of blind holes 31 are formed in the upper surface of the stand 30.
  • a pair of the blind holes 31 is formed communicating spatially with each of the speaker slots 12.
  • the stand 30 further includes a plurality of blocking members 32 extending respectively into the blind holes 31.
  • the positioning structure 40 includes a plurality of positioning members 41 and a plurality of resilient members 42. As shown in Fig. 5 , each of the positioning members 41 is disposed in a respective one of the blind holes 31, and each of the resilient members 42 is disposed in a respective one of the blind holes 31 between the stand 30 and a respective one of the positioning members 41.
  • Each of the positioning members 41 has a shoulder 412, and a catch protrusion 411 extending upwardly from the shoulder 412.
  • the shoulder 412 of each of the positioning members 41 has a first face 4121 abutting against the blocking member 32 in a respective one of the blind holes 31, and a second face 4122 opposite to the first face 4121.
  • each of the catch protrusions 411 is a convex protrusion that complements the concave hole-defining walls defining the reception holes 26 in the speaker casings 22.
  • each of the resilient members 42 is disposed between the second face 4122 of the shoulder 412 of a respective one of the positioning members 41 and the stand 30.
  • Each of the resilient members 42 biases a respective one of the positioning members 41 upwardly such that the shoulder 412 thereof abuts against a respective one of the blocking members 32 of the stand 30 and the catch protrusion 411 thereof extends outwardly from a respective one of the blind holes 31 to engage a respective one of the reception holes 26 in a corresponding one of the speaker casings 22.
  • the resilient members 42 are coiled compression springs in this embodiment.
  • a pair of the reception holes 26 is formed in each of the speaker assemblies 20, and a pair of the blind holes 31 (with an assembly of one of the positioning members 41 and one of the resilient members 42 disposed in each of the blind holes 31) is provided spatially communicating with each of the speaker slots 12.
  • the number of these elements is not limited to that described and may be varied as needed depending on, for example, the design and size of the speaker assemblies 20 and the stand 30.
  • the shapes of the reception holes 26 in the speaker casings 22 and the catch protrusions 411 of the positioning members 41 may also be varied as needed, and are not limited to the concave-convex configuration described above.
  • the speaker assemblies 20 may be detached from the stand 30 by simply pulling the speaker assemblies 20 out from the speaker slots 12. To reattach the speaker assemblies 20, the speaker assemblies 20 are slid back into the speaker slots 12, making sure that the bottom face of the speaker casing 22 is facing downward. In either case, each of the corresponding ones of the positioning members 41 receives a downward force by contact with the speaker casing 22 to thereby be pushed into the respective one of the blind holes 31 in the stand 30 against the biasing force of the respective one of the resilient members 42.
  • the positioning member 41 When the downward force is released from the positioning member 41 either as a result of the speaker assembly 20 being removed from the corresponding speaker slot 12 or as a result of a corresponding one of the blind holes 31 in the stand 30 being aligned with the positioning member 41 of the positioning structure 40, the positioning member 41 is biased to protrude back out from the corresponding blind hole 31 to thereby extend outwardly from the stand 30.
  • Fig. 7 illustrates the present invention in a state where one of the speaker assemblies 20 is fully detached from the flat panel display 10 and placed vertically on a supporting surface (not shown), and the other speaker assembly 20 is attached to the stand 30. Since the speaker casings 22 fully surround and therefore protect the speaker assemblies 20, either or both of the speaker assemblies 20 may be detached from the flat panel display 10 and placed on the supporting surface without damaging the speaker assemblies 20 or the supporting surface.
  • the speaker assemblies 20 may be easily attached to and detached from the flat panel display 10 without requiring the use of any tools. This provides convenience to users and reduces assembly time during manufacture. Furthermore, the configuration used to allow for attachment and detachment of the speaker assemblies 20 is such that damage to the speaker assemblies 20, the stand 30, and the display panel 13 is prevented. Finally, through the structure and material used for the speaker casings 22 of the speaker assemblies 20, not only is damage to the speaker assemblies 20 and a supporting surface prevented as described above, regardless of how the speaker assemblies 20 are positioned on the supporting surface, a superior vibration and resonance absorption effect is achieved as well.
